WJOLS 10.5005/jp-journals-10007-1146 REVIEW ARTICLE Role of Robotics in Whipple’s Surgery Role of Robotics in Whipple’s Surgery B Srinivas ABSTRACT In computer-controlled systems, the surgeon uses a Whipple is one of the most demanding and complex surgeries computer to control the robotic arms and its end-effectors, of the abdomen. It is the most commonly performed operation though these systems can also still use telemanipulators for for pancreatic cancer, the fourth leading cause of cancer death their input. One advantage of using the computerized in the United States. For patients with benign as well as malignant pancreatic tumors, it is believed that the robotic method is that the surgeon does not have to be present, Whipple procedure will be a major improvement over the indeed the surgeon could be anywhere in the world, leading traditional procedure. The robotic surgery involves five small to the possibility for remote surgery. incisions (one to accommodate a miniature camera), rather than a large incision and separation, not cutting of muscles.
